Period+ Breastfeeding 18 months

An

I’ve been breastfeeding the past 18 months and on 1/23 I got my first period. It lasted a little under a week i want to say. Yesterday I started spotting (pink CM) and it got heavier as the day went on and I’m still bleeding today (like a period but just a little less).

Do you think this is normal or should I call my gyno? Ive never spotted between periods before or had irregular cycles. Didn’t have this happen with my first child either.
